Railway Emergency Rescue: Training for Combat to Enhance Emergency Response Capability
In order to effectively improve the emergency rescue and disposal capabilities of the cadres and employees of the power supply system of China Railway Nanchang Bureau Group Co., Ltd. in response to train derailments, and to master the basic structure of vehicles and the operation process of rescue recovery equipment, an innovative on-site meeting for the recovery drill of the track maintenance vehicle switch area was held at the Huisheng Railway Heavy Industry Maintenance Base in Yong'an, Fujian on the afternoon of December 11.
From 0 to 160,000 kilometers, witnessing the power of China's progress through "railway scenery".
The Spring Festival travel season is an important window for observing the economy. It features the interaction between tradition and modernity, a balance between speed and warmth, reflecting the complex texture of the social and economic structure.
In January, the railway passenger volume increased by 12.1% year-on-year.
In terms of passenger transport, due to the combined demand for returning home for family visits and leisure vacations before the holiday, the volume of railway passengers continues to rise.
The China-Vietnam railway project has been approved by the Vietnamese National Assembly.
On February 19, the National Assembly of Vietnam voted to pass the resolution for the investment project of the Lao Cai - Hanoi - Haiphong railway construction.
In recent decades, with the continuous development of science and technology in our country, there have been corresponding breakthroughs in many technical aspects. At this time, we need to talk about: the technology of shaftless pump propulsion.
The working principle of a non-axial thruster
Compressed Air Supply: The shaftless propeller compresses a large amount of air to a high-pressure state through a compressor. This compressor can be driven by external energy sources such as electricity or fuel.
The 27th line of the rail transit conducts emergency rescue drills for tunnel collapses.
On December 27, at the construction site of the No. 9 standard section of the first phase of the Chongqing Rail Transit Line 27, rescue personnel from China State Construction Fifth Engineering Division are conducting toxic and harmful gas detection at the site of the tunnel collapse.
Can a stainless steel filter reduce pressure during filtration?
Stainless steel filters can perform pressure-reducing filtration. Pressure-reducing filtration is a commonly used filtration method that involves installing the filter on a pipeline and using a pressure-reducing valve to control the inlet and outlet pressure of the filter, thereby achieving pressure-reducing filtration of the fluid. The material of stainless steel filters is usually stainless steel, which has advantages such as corrosion resistance, high-temperature resistance, and pressure resistance, making it well-suited for pressure-reducing filtration.
How can the smoke from the oil filter shredder be eliminated?
The smoke from the oil filter shredder can be eliminated in the following ways:
1. Keep the equipment clean: Regularly clean the oil filter shredder to avoid residue inside the equipment affecting its performance.
2. Regularly replace the filter screen: During the use of the oil filter shredder, the filter screen intercepts smoke and dust, and prolonged use can lead to clogging. Therefore, it is necessary to regularly replace the filter screen to ensure the normal operation of the equipment.
3. Install a smoke exhaust system: Install a smoke exhaust system next to the equipment to promptly expel the smoke and dust generated by the oil filter shredder outdoors.
4. Pay attention to operational safety: When using the oil filter shredder, wear protective gear such as masks and gloves to avoid harm from smoke and dust to the body.
5. Use the equipment reasonably: Use the oil filter shredder according to actual needs, avoiding prolonged continuous use that can lead to overheating and excessive smoke and dust emissions.
The above methods are practical and can effectively eliminate the smoke from the oil filter shredder. However, it should be noted that different brands of oil filter shredders may have differences, and specific operational methods need to be adjusted according to the actual equipment.
How to check hydraulic valve solenoid valve?
The hydraulic valve solenoid valve is a device used to control the flow direction of hydraulic fluid. The hydraulic valve solenoid valve is usually controlled by an electromagnet. When the electromagnet is energized, the valve core moves, allowing the hydraulic fluid to flow from one port to another; when the electromagnet is de-energized, the valve core closes, preventing the hydraulic fluid from flowing to another port.
